I tried trading my 3 refined metal for a Schadenfreude, like the shop owner wants, but the bot says I need to offer 3 refined metal. Even though I already have added it and chosen 'ready'. Here's a screenshot: http://i.imgur.com/qm4v5.png

Thanks for any help.

To me it looks like the bots bug out whenever you offer more than 2 separate items of metal...
